Abstract:
The present invention relates to a method for producing low-halogen polybiphenylsulfone polymers, the polybiphenylsulfone polymers that can be obtained in this way, polybiphenylsulfone polymers having a content of polymer-bound halogen of less than 400 ppm, thermoplastic molding compounds containing said polybiphenylsulfone polymers, and the use thereof for producing molded bodies, fibers, films, membranes, or foams.
Abstract:
The invention relates to a photovoltaic system comprising a plastic carrier and photovoltaic module for installation on roofs. The plastic carrier (1) can be fastened directly on a roof substructure such that an additional roof covering can be dispensed with. The photovoltaic modules can be fastened on the plastic carrier (1) without screwing.
